Description

Floor heating laying structure

Technical Field

The utility model relates to an indoor heating technical field especially relates to a floor heating lays structure.

Background

In northern areas of China, the temperature is extremely low in winter and the duration is long due to the comprehensive influence of geographic factors, environmental factors and the like. Most of the northern areas need to adopt a heating mode indoors to spend the cold winter.

With the improvement of living standard and the rapid development of industrial and modern technology, in addition, the national advocates energy conservation, emission reduction and clean energy utilization in recent years. The floor heating is suitable for various energy media due to low price, and is widely applied in the northern areas.

The Floor Heating is short for Floor radiation Heating, and is called radiation Floor Heating, the whole Floor is uniformly heated by using a Heating medium in a Floor radiation layer as a radiator, and the Heating is achieved by conducting from bottom to top by utilizing the law of heat storage and upward radiation of the Floor. The low-temperature ground heating medium forms a temperature gradient gradually decreasing from the sole to the head in a room, so that the comfort of foot warming and head cooling is provided for people. The ground radiation heating conforms to the body-building theory of 'warm feet and cool tops' in traditional Chinese medicine, is the most comfortable heating mode at present, and is also a symbol of modern life quality.

When the traditional floor heating utilizes hot water to flow through a water pipe, heat is emitted, so that the heat contained in the hot water is transferred to a space needing to be heated through the heat transfer modes of heat conduction, convection and radiation of the water pipe.

The space needing heating usually corresponds to a heating ground, and the water pipe is laid under the limited ground, so that in the heating boundary, the existing water pipe is bent into a 'return' shape or a 'zigzag' shape in a winding and bending mode, and the heat dissipation area of the water pipe in a limited range is increased.

However, in the existing heating structure, the whole heat dissipation structure is formed by bending the same water pipe, the water pipe is led in from a room, and the bent coil is finally led out from the room.

Because the pipeline is too long and the number of bent channels is large, the pressure loss is large. Because the pressure loss is large, the pipeline is too thin, scale is easily formed in the pipeline, the wall surface is easily scaled, and the pipeline is further blocked. Once the pipe is blocked, the hot water cannot circulate normally, so that the temperature of the whole room is out of control.

According to the related theory of heat transfer science, the heat conduction resistance of the scale with the thickness of 1mm is 40 times of that of the pipe wall, and the heating quality is seriously influenced; according to related data, the water scale on the inner wall of the floor heating pipe can reduce the indoor temperature by about 6 ℃ every 1mm when the floor heating pipe is thickened in the running process, so that the heating effect is poor, and the energy is greatly wasted.

The hot water delivered by each user is distributed through the main water inlet pipe, and when the heating pipeline of the user is blocked by water scale, the flow of the main water inlet pipe is constant, so that the hot water delivered to other users can be increased. When the pipeline blockage conditions of each user are different, the main water inlet pipe can not uniformly convey hot water to each user, so that the heating temperature of each user is out of control.

According to the actual situation, the temperature difference of different rooms can reach 3-7 ℃ for the same user point, and the temperature difference is difficult to adjust, so that the body discomfort is caused by large temperature difference of each room.
